    Fix some minor chan_dahdi config load issues.
    
    * Address chan_dahdi.conf dahdichan option todo item about needing line
    number.
    
    * Make ignore_failed_channels option also apply to dahdichan option.
    
    * Don't attempt to create a default pseudo channel if the chan_dahdi.conf
    channel/channels option is not allowed.
    
    * Add a similar check for dahdichan in normal chan_dahdi.conf sections as
    is done in users.conf.
